Hi,

I attached the rear lamp wiring schematic below. I highlighted the wires that are relevant for the rear as well as which fuses to check.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below. Note: I had to cut the pic in two to make them readable. I did overlap them so you can follow from one to the next.
